本文提出可在二个相邻数字微波再生中继站之间插入一个直放式微波增音站,组成一个混合式中继段。用此办法可增加数字微波接力通信线路路由选择的灵活性及降低系统造阶。文章分析了这种混合式中继段的性能及设计公式,并介绍一个已通过技术鉴定的6GHz 直放式微波增音站设计方案。最后估算了用该站及二个再生中继站构成的34Mb/S 数字微波混合中继段的性能。
This paper proposes that a direct-coupled microwave enhancement station can be inserted between two adjacent digital microwave relay stations to form a hybrid relay section. This approach can increase the flexibility of the routing of digital microwave relay communications lines and reduce system order. The article analyzes the performance and design formula of this hybrid hops, and introduces a 6GHz direct-amplification microwave enhancement station that has passed the technical appraisal. Finally, the performance of 34Mb / S digital hybrid microwave relay station using this station and two regenerative relay stations is estimated.
